SPECIFICATION forming part of Letters Patent No. 582,300, dated May 1 1,1897.

Application filed February 19, 1896- Serial No. 579,902. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS M. MOORE, a citizen of the United States,residing at Somerville, in the county of Somerset and State of NewJersey, have invented certain new and useful Improvements inCultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements incultivators; and it has for its object, among others, to provide animproved pivoted-wheel cultivator having provision for the greatestlatitude of track adjustment to suit various crops.

I so construct the parts as to throw the working parts'of the machine ona practically straight line to the right or left, whether the cultivatoris working or not, and thus affording more positive and rapid action toavoid obstacles than where the lateral adjustment or movement is incommon only with the forward motion of the machine. The pivoted wheels,one on each side'of the machine, are provided with arms projectingforward. For the purpose of supporting the wheels and relieving the mainarch of the strain I provide a cross-bar which serves the doublefunction of guiding the machine and affording a support or brace for thewheels thereof. I also provide improved raising and lowering means forthe drag-bar and for applying the springpressure thereon, as well as agrooved pulley forming a part of such means. I provide for the guidanceof the machine by the hand and foot or feet of the operator whendesired.

I aim, further, at improvements in the details of construction of thecultivator as a whole and in its various parts whereby a more Theinvention in this instance resides in the peculiar combinations and theconstruction, arrangement, andadaptation of parts, all as more fullyhereinafter described, shown in the drawings, and then particularlypointed out in the claims.

The invention is clearly illustrated in the accompanying drawings,which, with the let-- ters of reference marked thereon, form a part ofthis specification, and in which Figure 1 is a side elevation of acultivator constructed in accordance with my invention. Fig. 2 is a planview thereof. Fig. 3 is a rear elevation with parts removed. Fig. 4 isan enlarged detail, in side elevation, with portions brokenv away. Fig.5 is a plan, on a smaller scale, of the frame with portions broken away.Fig. 6 is a face view of the grooved pulley. Fig. 7 is a central sectionthrough the same with the rope shown secured thereto. Fig. 8 is aperspective View of the two parts of the clamp-nut removed andseparated.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thetwo front cross-bars of the frame, which are arranged with a space orslot a between them, as shown in Fig. 2. B are the shafts or barssecured to the said cross-bars, and at their rear ends secured, as at a,to lugs projecting from the rear cross-beam O, as shown.

D is the seat, suitably supported, as, for instance, upon the transversebar 0, connecting the arms D, which are by preference of springmaterial, and their forward ends engaged in sockets or analogoussupports cl on the rear side of the rear cross-beam O. This rearcross-beam O is provided with a plural ity of holes 0, as seen best inFig. 3, which provide for all necessary adjustment of the pivot-wheels.

As seen in Fig. 2, E is a bracket or casting secured to the frontcross-bar A and projecting forward, and in this bracket or casting issupported the bolt E, on which is pivoted the draft-bar F, having aplurality of holes f near each end to provide for the necessaryadjustment of thedraft appliances.

F are suspended bars having a pluralityv of holes f near their lowerends, in which are adjustably connected the rods F the other ends ofwhich are linked with the rods F, which are connected at their rear endsto the drag-bars G,which drag-bars carry the shovels or teeth G,Whichmay be of any well-known or approved form of construction and secured totheir drag-bar in any desired manner.

The drag-bars,with the shovels or teeth, are designed to'be raised orlowered to regulate their depth of cut, and for this purpose I haveprovided the transverse shaft H, which is mounted in suitable hearingson the frame, and on this shaft are mounted the levers H, one near eachend, as seen best in Fig. 3, each lever having a spring-pawl h of knownconstruction adapted to engage a toothed segment or ratchet 1-1 securedto the frame so that the parts may be securely held in their adjustedpositions. Secured to this shaft near each end is a grooved pulleyLwhich has the V-shaped peripheral groove, as seen best in Fig. 7, andthe flange of the wheel or pulley is removed for a short distance, asseen at t in Figs. 6 and 7, so that the rope I may be thrown out of itspath to increase the frictional engagement on the pulley, and at thispoint the rope is held to the pulley by some suitable means, as thescreweye 1 passed through an opening i in the web of the pulley, as seenbest in Fig. 7, and receiving upon its end a nut i ,by which it may betightened when desired. The rope passes through the eye of the bolt, asseen in Figs. 6 and 7. This rope passes around the pulley and has oneend extended downward in a vertical direction,where it is secured to aneyebolt or the equivalent 1 011 the forward end of the drag-bar, as seenbest in Fig. 1, and its other end extends forward horizontally and ispassed through an opening in the upper end of the spring J, which iscurved and its other end secured to the forward end of the drag-bar,preferably by the eyebolt I or its equivalent, as seen in Fig. 1. Theend of the rope after passing through the upper end of the springisclamped bysuitable means, as the two-part clamp-nut K, the two partsbeing alike, as seen in Fig. 8, and each has a crooked groove 7.:therein, as seen, so that when the two are secured together and the ropeheld in the two coincident grooves it will be frictionally held againstendwise movementtherein. The two parts are secured together by suitablebolts or screws passed through the holes 7t therein. By adjustment ofthis nut the tension of the spring and its pressure on the drag-bar canbe regulated as occasion may acquire. As this spring and mechanism areduplicated on either side of the machine it will be understood how thedrag-bars may be raised or low-. ered at will and the tension orpressure of the springs increased or diminished, as required.

L is a bar arranged to the rear of and parallel with the frontcross-bars, but adapted to be reciprocated as may be required, and thismovement back and forth is accomplished by means of the rudder L, thehandle end of which extends to within convenient reach from the seat D,and its forward end is pivoted, as at Z, on the front cross-bar A, asseen best in Figs. 2 and 5, and depending from this rudder to the rearof its pivot is the pin L which extends between the bars Z, which extendrearward from the bar L, as seen in Figs. 2, 4, and 5, so as to engageeither one or the other according to the direction in which it isdesired to move the bar. It may sometimes be found desirable to movethis bar by the foot or feet of the operator, and for this purpose Ihave provided the stirrup L which, as seen in Figs. 1 and 4, dependsfrom the rudder and is designed to receive the foot of the driver, sothat the bar L may be moved in either direction. There may be one or twoof these stirrups, in Fig. 3 there being two indicated, one by fulllines and the other by dotted lines, the latter not being present whenthe stirrup L" is provided on one of the shovel-standards, as is shownin the same view, or both of these stirrups may be removed and the inneror independent teeth of the cultivator guided by two stirrups L M arethe pivot-wheels. They may be of any well-known or preferred form ofconstruction and are carried by the short axles ll which are mounted insuitable boxes or bearings, which may be ba1l-bearings, if desired, andthese hearings are supported in the lower ends of the hangers M whichare dependent from the swivels N, as seen in Figs. 1 and 3, and thevertical axis of the swivel is forward of the central line through theaxle, as indicated in Fig. 1, the support-s for the swivels being adjustably secured to the rear cross-beam C, so that the wheels may beadjusted in or out, as may be necessary or required. These swivels haveextending forward therefrom horizontally the yokes or bars N, as seenbest in Fig. 2, and which are pivotally connected, as at n, with theslide-bar L, the pivot being capable of adjustment into any one of theholes in the said bar.

0 are horizontal bars connecting the slidebar L with lugs on the frontface of the rear cross-beam G, as seen best in Fig. 5. They are pivotedat their ends.

P are plates having a plurality of holes 1), and these are adjustable inthe slot or space a between the cross-bars A A by means of the verticalbolts P, having nuts and washers, as shown, and adjustably connected tothese plates are the rods or bars 0, the other ends of which areconnected with the dragbars or the standards of the shovels.

The center standards, one or both, may be independent of the others, asshown in Fig. 3, or not, as may be found most expedient.

The parts of a cultivator not here illustrated and'such parts as areshown and not specifically described may be of any of the well-known orapproved forms of construction, and various modifications in detail ofthe parts hereinbefore specifically described may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

It will be readily seen that by the construction herein described itwill be possible, when track adjustment is desired or in the event ofthe arch with which the Wheels are pivotally connected being distortedor bent by sudden strain or wrench, to readily compensate therefor andmaintain a uniform tracking of the wheels by adjusting equivalently thepoint of connection to the projecting arms tened to the pulley at ornear its center, whereby but a single fastening device is necessary, andthe rope or chain is made to operate from either end, substantially asdescribed.

2. In a cultivator, the combination with a drag-bar and a springconnected therewith, of a grooved pulley, means for operating the same,and a rope passed around the pulley and secured to the same between itsends, and at its ends secured to the drag-bar and to the free end of thespring, substantially as speci fied.

3. In a cultivator, a drag-bar, and a vertical curved spring secured tothe front end of the drag-bar, combined with a rope or chain, and anoperating mechanism therefor; one end of the rope or chain beingfastened to the upper free end of the spring, to regulate its tension,and the other end fastened to the front 'end of the drag-bar, so as toraise it at this point, substantially as described.

at. In a riding-cultivator, two pivoted bearing-wheels, a rod forconnecting them, and upon which the wheels are adjustably securedcombined with the forwardly-projecting U- shaped yokes, and the rods Lupon which the yokes are adjustably pivoted, and whereby the yokes andpivots have a corresponding adjustment, as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.
